8 Claims.

This invention relates to improvements in washing machines.

Heretofore, in-washing machines, it has been common practice to utilize a cylindrical drum having an apertured periphery which is rotatable in a water containing outer shell. With this type of construction the water flows into and out of the apertures in the periphery of the cylinder during rotation of the latter to effect a cleansing action.

It is a general object of the present invention to provide an improved construction wherein there is no outer shell containing water and wherein a washing cylinder rotatable on a horizontal axis and having an imperforate peripheral wall contains both the water and the garments to be cleaned, there being means on the inner side of the peripheral wall of the cylinder for agitating and lifting the water to splash the same upon the garments as the cylinder rotates,- with all the water confined in said cylinder.

A further object of the invention is to provide a construction as' above described wherein there are liquid discharge outlets in an end wall of the cylinder and means rotatable with the cylinder normally closing said discharge outlets, said means being readily releasable, either when the cylinder is rotating or when it is idle, to permit the discharge of spent liquid. j

A further object of the invention is to provide in a washing machine of the character described having a drum rotatable on a horizontal axis and having a garment door in anend wall of said drum which is rotatable with the drum, means whereby the hinge for said door is non-rotatably supported and remains in a convenient fixed position so that opening of said door can be quickly accomplished regardless of the position in which the drum comes to rest after use.

Other objects of the invention are to provide a device of the class described wherein the cylinder has a cast peripheral wall and east end walls secured thereto; wherein the water and other washing liquids are admitted axially into the drum; wherein the drum is rotatable on supporting rollers engageable with the exterior of the peripheral wall of the drum; and wherein there is a circular trough positioned to receive liquid from the discharge outlets of the cylinder when the closure for the latter is moved to open position.

With the above and other objects in view, the invention consists of the improved washing machine and all its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawings, illustrating one complete embodiment of the preferred form of the invention, in which the same reference numerals designate the same parts in all of the views:

Fig. 2 is a view of the liquid discharge end of the washing machine, parts being broken away; Fig. 3 is atop view, parts being broken away; Fig. 4' is a view of the garment loading end of the machine, parts being broken away;

Fig. 5 is a fragmentary sectional view on an enlarged scale taken approximately on the line 5-5 of Fig.- 4; and

Fig. 6 is an enlarged fragmentary sectional view taken on line 66 of Fig. 5.

Referring more particularly to the drawings,

the numeral 8 designates a suitable supporting frame having a base 9, supporting legs Ill, corner uprights II, and a horizontally disposed'upper frame portion I2 supported by the upper ends of the uprights II. I a

A washing cylinder or drum I3 has a cast imperforate peripheral wall .l4 and end walls l5 and i6 bolted to outstanding flanges ll of the peripheral wall as at 18.

The outer side of the end wall lGis formed with an outstanding circular flange l9 and outwardly of the flange 19 is'a ring of openings 20 extending through the end wall l6 and forming dischargeoutlets for liquid. The end wall (6 is also formed with a central opening 21, and the end'of a driving sleeve 22 is bolted to the end wall l6, as at 23, with the bore of the sleeve in registration with the opening 2| of the end wall. The sleeve 22 extends outwardly and is journaled in a bearing 24 supported on a bracket 25. The

bearing 24 and bracket 25 support a housing 26 for a driving gear 21, and the driving gear is keyed to the sleeve 22 to drive the latter and the washing cylinder I3.

Referring to Fig. 2, the gear 21 is driven by a pinion 28 mounted rigidly on a shaft 29. The shaft 29 is journaled in the housing 26 and also carries a bevel gear 30 rigidly thereon which is driven by a-bevel pinion 3| mounted rigidly on a shaft 32. The opposite end of the shaft 32 has a rigidlymounted pulley 33 thereon which is driven by endless belts 34 operating in conjunction with a pulley 3'5 onthe' drive shaft of a motor 36.

, (see Figs. 1 and 3). formed with an external annular groove 52 within provided with a float controlled valve 45, or other means for controlling the delivery of soap solution, and the valve 39 for the water tank 31 may be operated by a hand rod which is connected by levers 41 and 48 with the rod 48 for the valve 39. It is thus apparent that both water and soap 'solution may be fed axially into the washing cylinder through the medium of the inlet pipe 42 and that the drive sleeve for the washing cylinder when driven by the electric motor 35 is rotatable around the inlet pipe 42.

Keyed to the exterior of the drive sleeve 22, but

slidable longitudinally thereon, is a shifter collar 50 having pairs of apertured lugs 5| projecting radially outwardly therefrom at spaced points The shifter collar is also which a shifter ring 53.fits so that the shifter collar is rotatable within the shifter ring 53. The shifter ring is provided with oppositely disposed projections 54 which are engaged by the ends of a shifter fork 55. The fork 55 has a shifter lever 55 projecting outwardly therefrom which is fulcrumed as'at 51 to a bracket 58 projecting from the gear housing 25. The shifter lever 55 is operable by a rod 58' having a conveniently positioned handle 59. It is thus apparent that the manipulation of the handle 59 will cause axial movement of the shifter collar 58 on the drive sleeve 22 even while the collar is rotating with the drive sleeve.

Adjustable links 5!! have one end pivotally connected to the projecting lugs 5| of the shifter collar and the other end pivotally connected to bell crank levers. 5 as at 52. The bell crank levers are pivotally supported, as at 63. on the end wall |6 of the washing cylinder, and the inner ends of the bell' crank levers are pivotally connected, as at 54, with a valve or closure ring 55. This ring has an inner circular flange 56 which fits against the outer surface of the circular flange l9 on the end wall of the cylinder, as shown in Fig. 1, and the closure ring also has an outer clrcular flange 51. It is apparent that when the handle I 9 on the rod 58 is pulled outwardly it will act through the lever 55, shifter ring 53. shifter collar 50; links 50, and bell cranks 5| to pull the closurefring' outwardly out of sealing contact with the liquid dischargeopenings 28 in the end wall of the cylinder, and thismay be accomplished either when the cylinder is rotating or when it is idle.

Liquid discharged from the cylinder when the closure ring 55 is opened is received in a circular trough 58 carried by the frame 8. The trough has a front guard wall 59 which extends inwardly beyond the flange 6! of the closure ring 55, and the inner edge of the guard wall 58 is hooked as at 10 whereby when the closure ring is opened all liquid being discharged is directed into and confined in the trough 68. The trough 58 has a bottom opening leading to a suitable P int of discharge.

The outer surface of the peripheral wall H of the washing cylinder is formed with a projecting and splash said water back on the clothes.

2,313,152 controlled by a valve 39,- and a delivery pipe 40 circular rib 1| having a flat outer surface to run on rollers 12 (see Fig. 4). These rollers are rotatably supported on brackets 13 projecting upwardly from the bottom of the frame 8 and form a support for'the washing cylinder during its :0- tating movement.

The inner surface of the peripheral wall H of the washing cylinder is cast with inwardly projecting ribs 74 which extend in an axial direction and with other flatter ribs 15 which extend at an angle to the axis, as shown in Figs. 1 and 4. These ribs are adapted to lift water in the lower portion of the cylinder, as the cylinder rotates, The ribs also keep the water in an agitated condition and keep the garments in motion. The use of these ribs which are not perforated in conjunction with a cylinder having a peripheral wall without perforations, produces a very effective washing action.

The end wall |5 of the washing cylinder has a large central garment opening 15 surrounded by an outwardly projecting circular flange H. A- circular door 18 (see Figs. 4, 5, and 6) has an inwardly'extending circular flang 19 adapted to fit around the flange 1'! of the end wall opening, asv

shown in Fig. 6. The circular flanges 11 and 19 have cooperating angled surfaces to produce a wedge fit for the door. In addition the flange 19 of the door has three or more bayonet. slots 8|, as shown in Fig. 5, which cooperate with rollers 82 projecting from the flange H to permit locking of the door to the end wall of the washing cylinder by a partial rotation of the door to bring the rollers 82 into engagement with the inner ends of the bayonet slots 8|, as shown in Fig. 5.

The outer side of the flange 19 of the door has outwardly projecting spaced flanges 83 and 84 forming a groove 85 cooperating with a hinge ring 85 (see Fig. 6). The hinge ring 86 has hinge projections 81 from its left-hand side pivotally connected as at 88 with fixed hinge members 89 secured to the frame of the machine.

The hinge ring 85 fits loosely within the groove 85, whereby, when the cylinder is rotating, the.

door 18 can rotate with the cylinder and-within the non-rotatable hinge ring 86. Heretofore it has been customary to hinge the doors directly to the end wall of the cylinder, with the resultv that when the cylinder was stopped the hinge would usuallybe in an inconvenient position for opening the door to remove the garments or load garments into the cylinder. With the present arrangement the hinge is always in a proper left-hand position and no matter where the cylinder comes to rest the door may be quickly and conveniently opened.

From the above it is apparent that the improved construction, wherein no outer water containing shell is utilized and wherein all the water is confined in the rotating cylinder and acted the other end wall of the washing cylinder controlled by the closure ring, either when the cylinder is rotating or when it is idle, permits quick sainddcomplete emptying of the cylinder when de- Although only one form of the invention has been shown and described, it is obvious that various changes and modificatio'ns may be made without departing from the spirit of the invention, and all of such changes are contemplated as may come within the scope of the claims.
